Water supply device

Abstract

To provide a water supply device in which a filter does not float up from water even when a filter formed to be low cost and lightweight is used. [Solution] A water supply device 1 has a filter section 2, a hose 3, and a pump 4. The pump 1 has a discharge section 5 that discharges water sucked up through the filter section 2. The filter section 2 is formed by a filter and an adapter 6 that connects the filter to the hose 3. The adapter 6 has a weight that exceeds the buoyancy of the filter in water. To keep the construction low cost, the filter is made of foamed polyurethane, but the adapter 6 has a weight that exceeds the buoyancy of the filter, which has the effect of preventing the filter from floating up and allowing for stable water intake.

Description

[Technical Field]

[0001] The present invention relates to a water supply device. [Background technology]

[0002] There is a known water supply device that uses leftover bath water to flush toilets. Patent Document 1 describes a device in which the end of a water supply hose connected to a pump is immersed in stored water such as a bathtub, and the water is pumped up and supplied to a tank. The end of the water supply hose that is immersed in the bathtub is fitted with a filter consisting of a coarse mesh filter and a hollow metal body that acts as a weight, and is configured to prevent the intrusion of foreign matter such as dust. The water supply device described above has a feature that the filter at the tip of the water supply hose has a weight, so that the filter part side does not splash up above the surface of the stored water, allowing for stable water absorption.

[0003] In addition, in the case of water purification systems for disasters, it is necessary to pump up water containing impurities from reservoirs of ponds and rivers, and a filter is required to remove impurities when pumping water with a water supply pump. For water supply pumps to be used in emergencies such as disasters, it is preferable to have a lightweight, simple structure that does not take up much space.

[0004] [Patent Document 1] Japanese Patent Application Publication No. 2002-38562 Summary of the Invention [Problem to be solved by the invention]

[0005] The filter unit placed in the stored water is the first part to filter the water in the purification process, so it is prone to getting dirty and needs to be replaced frequently. However, components that combine a mesh filter and a weight like the one described above tend to be expensive, and replacement costs are high. The present invention was devised in response to these circumstances, and its objective is to provide a water supply device in which the filter does not float up from the water, even when a low-cost, lightweight filter is used. [Means for solving the problem]

[0006] In order to solve the above problems, the present invention has the following configuration: A water supply device having a filter section, a hose, and a pump, wherein the pump has a discharge section that discharges water sucked up through the filter section, the filter section is formed by a filter and an adapter that connects the filter to the hose, and the adapter has a weight that exceeds the buoyancy of the filter in water.

[0007] The present invention is also characterized in that the filter is made of foamed polyurethane in the water supply device.

[0008] The filter is then inserted into the water supply system and fitted to the adapter. The adapter ... [Effects of the Invention]

[0009] The water supply device of this invention uses a filter made of foamed resin, which can be manufactured inexpensively, and is characterized by having a connection adapter for connecting the filter to the hose, which has a weight greater than the buoyancy of the filter to prevent the filter from floating up. This has the effect of preventing the filter from floating up when using an inexpensive filter, and allowing for stable water intake. [Brief explanation of the drawings]

[0010] [Figure 1] FIG. 1 is a schematic diagram illustrating an example of a water supply device. [Figure 2]FIG. 2 is an explanatory diagram illustrating the configuration of a filter unit. DETAILED DESCRIPTION OF THE INVENTION

[0011] Figure 1 is a schematic diagram showing an example of a water supply device 1. The water supply device 1 is mainly composed of a filter unit 2, a hose 3, and a manual pump 4. The pump 4 is configured to suck up water through the filter unit 2 and discharge it from a discharge unit 5.

[0012] 2 is an explanatory diagram showing the configuration of the filter unit 2. The filter unit 2 is made up of a filter 10 and an adapter 6. The filter 10 is made of a foam material such as polyethylene, and is formed to have a specific gravity lighter than water and to be water permeable. The filter 10 is formed as a cylindrical body with a circular opening 7 at only one end that communicates with the interior.

[0013] The adapter 6 is made of a material such as brass, stainless steel, or steel, and has a filter mounting portion 8 that is inserted into the opening 7 of the filter 10, a disk-shaped flange portion 9 that abuts the end face of the filter 10, and a hose mounting portion 10 to which the hose 3 is attached. The weight of the adapter 6 is set to be heavier than the buoyancy of the filter 10, so that the filter 10 does not float but remains on the bottom of the water.

[0014] The filter mounting portion 8 fits into the circular opening 7 by being inserted into it, preventing it from easily falling out. The disk-shaped flange portion 9 has the same outer diameter as the filter 10, and its outer periphery is knurled. The flange portion 9 forms the contact surface against which the end face of the filter 10 contacts, and by adjusting its width, the weight of the adapter 6 can be reduced.

[0015] Although the water supply device 1 shown in FIG. 1 uses a manual pump 4, it may be an electric pump. [Industrial Applicability]

[0016] This device can be used as a water purifier for daily life purposes other than drinking, such as toilets in emergencies, face washing, and body cleansing showers. [Explanation of symbols]
